Yankees shortstop Derek Jeter received a cortisone shot in his left ankle and his presence in the opening day lineup is in doubt, reports Jon Heyman of CBSSports.com. Should Jeter be forced to start the season on the disabled list, Eduardo Nunez will serve as the everyday shortstop. Jeter fractured his ankle during last season's ALCS and had surgery to repair it Oct. 20. He's been able to accrue 12 plate appearances this spring but has continued to have issues with the injury. And the Yankees' spring of horrors continues. Instead of an opening-day infield of Mark Teixeira, Robinson Cano, Derek Jeter and Alex Rodriguez, it's possible the Yankees line up with Juan Rivera, Cano, Nunez and Kevin Youkilis. And that's without mentioning Curtis Granderson and his broken arm.
